If you want to remove the fuel injector plug from a 1985 Corvette, you've come to the right place. This paragraph will introduce you to the process and some of the key considerations. Firstly, it's important to note that the fuel injector is a crucial component of your Corvette's fuel delivery system, and maximizing its performance and efficiency is key. While some people opt for a replacement injector manufactured by the original GM supplier, others choose to rebuild their existing injector to meet or exceed factory specifications. Whether you're removing the fuel injector plug for maintenance, repair, or replacement, it's important to follow the correct procedures to avoid causing any damage. One important consideration is the use of a thin 90-degree scribe tool to remove the clips that hold the plug in place. By pushing the wire clip towards the injector and then pulling up on the connector, you can access and remove the fuel injector plug.

What You'll Learn
Using a 90-degree scribe tool to remove the clips
To remove the clips without causing any damage, you can use a 90-degree scribe tool. This is a thin tool that can be inserted under the clips, allowing you to lever them out without too much force. The 90-degree angle of the scribe tool is important as it allows you to get under the clips effectively.
Firstly, you need to locate the wire clips. These can be found attached to the fuel injectors. Push the wire clip towards the injector, and then pull up on the connector. This will give you some room to work with.
Now, take your 90-degree scribe tool and insert it under the clips. You should be able to gently lever them out without causing any damage. This method is much easier than simply squeezing and pulling, and it also reduces the risk of breaking the plastic.
A 90-degree pick is also a useful tool for this task and can make the process even quicker. With this tool, you can remove all four clips in under 30 seconds. Curved or angled picks are also handy for this job, as they can easily get under the clips and provide some leverage.

Purchasing a replacement injector
When purchasing a replacement injector for your 1985 Corvette, there are a few things to keep in mind. Firstly, it is important to identify the correct type of fuel injector for your vehicle. The fuel injector you choose should be compatible with the specific model and year of your Corvette. Check manufacturer sites and listings for compatible vehicles.
You can find replacement injectors from a variety of retailers, including online marketplaces like eBay and Amazon, as well as automotive parts stores like Summit Racing. When searching for a replacement, look for injectors that match the specifications of your Corvette's original equipment. This includes factors such as impedance (measured in Ohms), voltage (typically 12V), and fuel flow rate (measured in lbs./hr.).
For example, some common specifications for 1985 Corvette fuel injectors include an impedance of 14.4 Ohms, a voltage of 12V, and a flow rate of 24 lbs./hr. It is important to match these specifications as closely as possible to ensure optimal performance and compatibility with your vehicle.
Additionally, consider the condition of the replacement injector. You can choose between new, used, or rebuilt injectors. New injectors will be more expensive, but they offer the advantage of being in pristine condition and typically come with a warranty. Used injectors can be a more affordable option, but they may have varying levels of wear and tear, so it is important to assess their condition carefully before purchase. Rebuilt injectors, such as those offered by Corvette Salvage, are another option where the injectors have been refurbished and can provide a balance between cost and reliability.

Using a retainer to remove the injector
To remove the fuel injector plug on a 1985 Corvette, you will need to purchase a retainer ring removal tool. This tool is designed to remove the locking retainer ring that secures the fuel injector in place. Here is a step-by-step guide on how to do it:
Step 1: Obtain the necessary tools, including the Fuel Tank Lock Ring Wrench Tool (T90T-9275-A or T86T-9275-A) and any other appropriate tools.
Step 2: Locate the fuel injector plug on your 1985 Corvette. It is usually located near the fuel tank sending unit.
Step 3: Place the wrench tool onto the locking retainer ring. The locking retainer ring is what secures the fuel injector in place. Make sure the tool is properly aligned and engaged with the ring.
Step 4: Turn the wrench tool counterclockwise to loosen and remove the locking retainer ring. Be careful not to strip the threads or damage the ring.
Step 5: Once the locking retainer ring is removed, you can carefully pull the fuel injector out. It may require some wiggling or gentle force, but it should come out without much difficulty.
Step 6: If needed, you can now clean, repair, or replace the fuel injector as desired. Just make sure that any replacement parts meet or exceed factory specifications for optimal performance and safety.
Step 7: Reinstall the fuel injector by first placing it back into its housing and then securing it in place with the locking retainer ring. Tighten the ring clockwise with the wrench tool, being careful not to overtighten it.
It is important to consult a professional mechanic or a factory service manual if you are unsure about any steps or procedures. Working on fuel injectors can be complex and requires careful attention to avoid damage or injury. Always prioritize safety and follow proper maintenance guidelines for your vehicle.

Running seafoam in the tank
To run Sea Foam through the fuel tank of your 1985 Corvette, follow these steps:
First, locate the fuel tank and remove the fuel injector plug by pushing the wire clip towards the injector and pulling up on the connector. This will allow you to access the fuel tank. Next, pour Sea Foam Motor Treatment directly into the fuel tank. Sea Foam is a fuel and oil additive that helps clean and lubricate your fuel system, including fuel injectors and carburetors. It removes harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas.
For regular fuel system maintenance, add 1 ounce of Sea Foam per gallon of fuel. If you're looking to do a deeper clean, add 2 or more ounces of Sea Foam per gallon of fuel. The more Sea Foam you add, the better it cleans! You can also use Sea Foam in injector cleaning machines by mixing it 50/50 with gas.
Sea Foam is made from petroleum ingredients and is safe and effective to use in all types of gasoline or diesel fuels and fuel blends. It does not contain harsh detergents or abrasive chemicals that can harm your engine or fuel system components. Sea Foam has been trusted since 1942 to help engines and equipment run better and last longer.
